Systematics of the Auroral Boundary as Indicated by Particle Precipitation.
Abstract
This thesis examined several ways of grouping data acquired by the DMSP/F7 satellite's electron and ion spectrometers, and used that data to decide the relationship between the latitude of the equatorward boundary of the electron and ion diffuse aurora. The statistical analysis was done with the SPSS computer package and data from the Special Sensor J/4 on board the Defense Meteorological Satellite Program F7 (Block 5D) spacecraft. The analytic technique used was bivariate linear regression, with the General Linear Test for the equality of two regression lines being used to compare different regression lines. The analysis of precipitating electrons and ions above the polar regions at about 840 kilometers found that the precipitation at different measured boundaries according to their magnetic local times of occurrence. Three hour wide bins were attempted, and were found to be less desirable than one hour wide bins. It was found that measured boundaries from the two poles can be combined in a single regression line.
